1Large Plastic Niche OverviewREAD THIS FIRST BEFORE INSTALLING1. Ensure that the electrical system of your pool conforms with the following requirements of theNational Electrical Code (NEC), and all local codes and ordinances. A licensed or certified electricianmust install the electrical system to meet or exceed those requirements before the Large PlasticNiche (fixture-housing) is installed.2. Some of the NEC requirements are as follows: The lighting circuit must have a Ground Fault Circuit Interrupter (GFCI), and have an appropriatelyrated circuit breaker. The junction box or the low voltage transformer is located at least 12 inches above water level and atleast 48 inches from the edge of the pool, see Figure 1 below. The light fixture and all metal items within five (5) feet of the pool must be properly electricallybonded. The niche must be properly installed so the pilot screw hole is at the 12 o’clock position and the topedge of the Underwater Light’s lens is at least 18 inches below the surface of the water in the pool,see Figure 1. This requirement may be less than 18” if the fixture is installed in an area of theswimming pool that is not used for swimming and the lens is adequately guarded to keep any personfrom coming in contact with the lens. Consult your local codes and ordinances and the NationalElectrical Code (NEC).48TO TOP OF LENSFigure 1.The niche is properly electrically bonded and grounded using the NO. 8 AWG ground connector located at therear of the niche, see Figure 1.Use only Pentair lighting fixtures in this niche to ensure proper bonding and grounding connections.Large Plastic Niche Installation Guide
2Large Plastic Niche Concrete/Gunite Pool InstallationThe following steps describe how to install the large plastic niche to the pool rebars, connect the metal conduitto the niche and connect the bonding/grounding wire to the outside of the niche. Also, included are installationinstructions for the optional Cord Seal Grommet kit (sold separately). For more information, see page 3.DANGER RISK OF ELECTRICAL SHOCK OR ELECTROCUTIONWARNING — Risk of electrical shock or electrocution.For proper bonding and grounding connections, use only Pentair underwater Light fixtureswith this niche-fixture housing. Failure to do so could create an electrical hazard which wouldresult in death or serious injury to pool users, installers and others.1. Locate position on the vertical surface where the niche and light is to be installed. The top of the lightlens must be a minimum of 18” below normal water level.2. Connect the PVC conduit to the niche using a PVC solvent, such as Weld-On 710 PCV Cement.Note: If required, a 45 PVC 1” to 3/4” conduit elbow adapter is provided with the kit. Whengluing the PVC elbow to the niche, ensure to insert the elbow with the niche facing up, to avoidglue running into the inside of the niche.3. Secure the niche-fixture housing to the rebar with tie wires. Orient the niche so that the pilot screwreceptacle is located at the top of the niche.4. On the rear of the niche is a brass terminal called the bonding lug for securing the bond wire. Thebond wire is a #8 AWG wire that connects the bonding lug to the bonding grid. The bonding grid is allother metallic items within five (5) feet of the pool including the rebar connected together. For moreinformation, see NEC 680.26 code requirement.5. Inside the niche is a brass terminal called the grounding lug. The grounding lug is the opposite side forthe bonding lug. A #8 AWG insulated solid or stranded bonding/grounding wire must be installedthrough the conduit from the junction box to the grounding lug inside the niche. This connectioninside the niche must be sealed with a listed sealant such as 3M Scotchcast Potting Kit 2136 orequivalent (see page 5 step 13). For more information, see NEC 680.23 code requirement.PVC 1” to 3/4”conduit adapter(provided in kit)Rear bonding lug(connect bondingwire here)Large Plastic Niche (side view)6. Support conduit to hold the Large Plastic Niche at the proper distance in front of rebar so that thefront of mounting ring is flush with the desired finish surface.7. If pool surface is to be plastered, you must allow proper concrete cut-back for plaster thickness.Finished concrete surface must be cut-back behind the niche flange, see Detail A of Figure 1 onpage 1). Finished area surrounding niche must be flat and flush with the front face of the niche. Thisensures a snug fit between light and wall.Large Plastic Niche Installation Guide
3Large Plastic Niche Concrete/Gunite Pool Installation(with optional cord seal grommet)Before installing the large niche, read through the installation steps. Also, if required by local code, included areinstallation instructions for the optional cord seal grommet assembly, which can be purchased separately(P/N 670044).To install the bonding wire (and optional cord seal grommet) in the niche:1. The seal cap is factory installed in the conduit thread.2. Route the bonding/ground wire and the light cord through the conduit and seal cap into the inside ofthe niche.3. Pull the required length of light cord through the niche.4. On the rear of the niche is a brass terminal called the bonding lug for securing the bond wire. Thebond wire is a #8 AWG wire that connects the bonding lug to the bonding grid. The bonding grid is allother metallic items within five (5) feet of the pool including the rebar connected together. For moreinformation, see NEC 680.26 code requirement.5. Inside the niche is a brass terminal called the grounding lug. The grounding lug is the opposite side forthe bonding lug. A #8 AWG insulated solid or stranded bonding/grounding wire must be installedthrough the conduit from the junction box to the grounding lug inside the niche. This connectioninside the niche must be sealed with a listed sealant such as 3M Scotchcast Potting Kit 2136 orequivalent (see page 5 step 13). For more information, see NEC 680.23 code requirement.Seal capBonding wireBonding lugLarge Plastic Niche Installation Guide
